鸭河口水库土壩设计,先后曾作了三次修改,有利的配合施工,对水库按期拦洪起到重大作用。拦河壩工程采用沙壳塑性心墙式土壩,共长3,300米;主要?段在台地用河槽,长1,400米,壩高为28米及31米,均采用上游作粘土铺盖防渗的形式。壩基正处在鸭河、白河汇流处;白河河床较缓,沉积大量较细沙层;鸭河河床较陡,冲积物多为卵 Duck River Estuary dam design, has made three changes, the favorable cooperation with the construction of the reservoir on a regular basis play a significant role.
